If your Wolf Boiler indicates a fault with the throughput sensor, meaning the lead or sensor is faulty or not connected, check the lead and replace the sensor if required.
What to do if no flame is established in my Wolf Boiler?
If no flame is established during burner start in your Wolf Boiler, check the gas supply pipe and open the gas tap if needed. Also, inspect the ignition electrode and ignition cable. If the issue persists, press the reset button.
How to fix TBV excess temperature in Wolf Boiler?
If your Wolf Boiler shows a TBV excess temperature error, it means the flow temperature has exceeded the limit, or the heat exchanger is severely contaminated. To resolve this, check the system pressure, heating circuit pump, and the HC pump's step switch. Vent the heating system and press the reset button. If the problem continues, clean the heat exchanger.
Why is there a lack of air in my Wolf Boiler?
A lack of air in your Wolf Boiler typically means the differential pressure switch is not ON. Try pressing the reset button. Also, check the silicone hoses connected to the differential pressure switch, inspect the flue gas system and gas fan, and verify the differential pressure switch itself.
How to troubleshoot a faulty differential pressure switch in Wolf Boiler?
If the differential pressure switch in your Wolf Boiler does not switch OFF, try pressing the reset button. If the issue persists, the differential pressure switch may need to be replaced.
How to solve flow monitoring issues in a Wolf Boiler?
Flow monitoring issues in your Wolf Boiler, indicated by an excessive temperature change (Flow temperature 2, flow temperature 1 > 12 K), can be addressed by venting the heating system and checking the system pressure. Also, ensure the heating circuit pump is functioning correctly.
Observe all national safety regulations and installation requirements.
Commissioning must only be carried out by the system installer or a commissioning engineer designated by him.
The system installer must hand the operating instructions to the system user and instruct him/her in the operation of the system.
Technical classifications and operating parameters for the boiler.
Determine the installation location for the gas fired boiler; maintain the specified minimum clearances.
For installation of the gas fired boiler inside a cupboard note the following:
Laying the gas pipe as well as making the gas connections must only be carried out by a licensed gas fitter.
Wolf connection sets (accessories) are available for installation on finished and unfinished walls.
For the cold water and DHW connection, we recommend the installation in accordance with DIN 1988.
